I just got an Arrma Granite and on the first run the car suddenly stopped and i noticed the ESC was blinking red. I had been using it for about 15 mins and assumed the battery just died. This is my first Arrma and on my Traxxas cars they don't suddenly stop when the battery dies since they are NIMH. The book says it could be overheating, however i cant imagine that is the case. It is 40 degrees outside and its not hot to touch. Any ideas? Thanks
